Lice-cycle GHG emissions

Battery electric trucks have the lowest life-cycle GHG emissions

This is true from 16-40t trucks, according to a study by Ricardo Research (2020), which compared emissions of the differing drivetrain technologies based on a WTW approach. The emission-saving potential of electric vehicles (EVs) increase when entirely powered by renewable energy (up to 81%) compared to a fossil-powered alternative as shown by study ICCT (2021) undertaken in passenger cars. As battery-eletric trucks (BETs) have outstanding energy efficiency, lifecycle emissions decrease with every additional kilometre driven, meaning that long-distance trucks have particularly high emission-saving potential.

Battery electric trucks offer a dramatic improvement of energy efficiency

BETs offer a dramatic improvement of energy efficiency, i.e. the ability to drive a greater number of kilometres on the same amount of energy. The JRC, EUCAR and Concawe (2020) have updated their joint evaluation of the WTW energy use and Greenhouse gas (GHG) emissions for a wide range of powertrain options. Considering only zero-emission technologies on Wheel-to-Well (WTW) basis, BETs using green electricity - both regional and long-haul - are 2.6 times more energy efficient than the green hydrogen-powered fuel cell equivalent. Although synthetic fuels were evaluated for cars rather than trucks, as an indication a battery electric car using green electricity is 6.9 times more energy efficient than a combustion vehicle using e-fuel.

GHGs and air pollutant

Battery electric buses do not produce local GHGs and air pollutant emissions

Battery-electric buses (BEBs) do not produce local GHGs and air pollutant emissions, providing considerable health benefits, particularly in cities. Because they are powered by electricity, the higher powertrain efficiency means that BEBs emit 73% less CO2 equivalent than diesels, rising to 90% if powered by 100% renewable sources. In contrast (according to ICCT (2022)),Compressed Natural Gas (CNG) CO2 emissions are nearly 30% lower than a diesel, but its higher energy consumption - 24-50% per kilometre - reduces this advantage. In addition, methane is a potent GHG with a global warming potential more than 80 times greater than CO2 over a 20-year period; unintended leakages during extraction and transport further exacerbate the situation.

Intermodality

BETs will contribute to the further greening of intermodal transport

BETs will contribute to the further greening of intermodal transport, as well as improving the overall energy efficiency of freight logistics. Synergies between rail, road transport and inland waterways are crucial to the logistics system. These offer benefits for the whole supply chain, as intermodal transport helps reduce congestion in urban areas while potentially increasing capacity in and around cities. Tangible examples of intermodal links have been successfully deployed in Paris’ metropolitan area. Companies such as IKEA and Franprix supply stores in Paris are using a combination of electric ships and electric road transport solutions for the last-mile segment.

Electricity grid

With smart grid technologies, the grid would need little adaptation for BETs and BEBs.

With smart grid technologies, the grid would need little adaptation for BETs and BEBs. Uni- and bi-directional charging enables a double optimization of the load at the depot. Optimising the grid connection and allowing the monetisation of the vehicles' flexibility capabilities makes them valuable assets, even when parked: it also provides the grid with supplementary battery capacity. Vehicle-to-grid (V2G) is performed at much lower power levels than in regenerative braking or fast charging.

Cost

By 2030, 99.6% of new BETs will be cheaper to own and run than diesel trucks

By 2030, 99.6% of new BETs will be cheaper to own and run than diesel trucks while carrying the same weight of goods over the same distance and journey time, according to a study by TNO (2022). This study is based on the total cost of ownership (TCO), the most important economic indicator for a truck. It covers those deployed in urban and regional delivery over distances of 300 km as well as long-distance trucks travelling 800km/day. Due to the savings from using electricity rather than diesel, the cost-saving potential of BETs increases with every additional kilometre driven, meaning that by 2035, long-distance trucks will be the most cost-efficient solution in Europe.

Investment costs of battery elecric buses

Higher investment costs of BEBs offset by lower electricity consumption and maintenance costs.

Similarly, the higher investment costs of BEBs are offset by their lower electricity consumption and maintenance costs (in Spain and Latin America in 2021 and in Italy, US and UK by 2023). Bocconi University and Enel Foundation (2021) integrated well-known TCO (the initial investment in purchasing vehicles and the charging infrastructure, plus the operational and maintenance costs) with peculiar to BEBs circular economy revenue streams, by the second life of batteries and V2G. This explains why buses are now the fastest-growing zero-emission vehicle segment, making up 23% of new city buses in 2021, up from 16% in 2020. Considering the revenues from V2G and second life, BEBs are more cost effective than diesel and CNG buses.

Payload

Urban and regional trucks can already have as much payload capacity as their diesel counterparts

Urban and regional trucks can already have as much payload capacity as their diesel counterparts today, according to a recent study by TNO. While the battery of an electric long-haul truck currently may weigh several tonnes, depending on its size, the so-called 'ZEV weight allowance' grants an additional two tonnes to zero emission trucks on European roads. This, along with improving vehicle energy efficiency and battery energy density, will eliminate any payload loss by the end of the decade, even for long-distance trucks with 800km range.

Range

BETs already have more than sufficient range to cover freight transport routes in Europe

BETs already have more than sufficient range to cover freight transport routes in Europe, something that will continue to improve. With the compulsory 45-minute break every 4.5 hours, and given that they have a maximum permitted speed of 90km/h, trucks will never drive more than 400 km without having to stop. Tesla has begun deliveries of the ‘Tesla Semi’, a clean-sheet design BET with a real-world range of 800km when fully loaded. The EU’s Weights & Dimensions Directive allows ZETs to be increased by two tonnes over that of diesel trucks. This allowance alone already increases the payload-neutral range of electric trucks by over 300km.

Extreme conditions

BETs are as competent as diesel trucks in extreme cold.

BETs are as competent as diesel trucks in extreme cold. In February 2021, Volvo Trucks, ABB and Vattenfall - together with a local mining company - ran a trial on replacing the diesel transport of iron ore with BETs. The ore is taken from a North Sweden mine to the railway transfer station, in temperatures of -30C°. The BETs were used for the journey from the mine to the transfer station where they could unload the cargo while recharging batteries following a 280km round trip normally undertaken by diesel-powered vehicles. The Polar Winter Project proved the feasibility of electric transportation in extreme conditions. The BETs were able to drive the entire distance - including 140km with 14t of ore on board, at temperatures as low as -32C° - while taking the same amount of time as the diesel trucks.
